A major group of natural killer (NK) T cells express an invariant V 14 T cell receptor (TCR) specific for the lipoglycan-galactosylceramide (-GalCer), which is presented by CD1d. These cells may have an important immune regulatory function, but an understanding of their biology has been hampered by the lack of suitable reagents for tracking them in vivo. Here we show that tetramers of mouse CD1d loaded with-GalCer are a sensitive and highly specific reagent for identifying V 14 NK T cells. Using these tetramers, we find that-GalCer–specific T lymphocytes are more widely distributed than was previously appreciated, with populations of largely NK1. 1 but tetramer-binding T cells present in the lymph nodes and the intestine. Injection of-GalCer leads to the production of both interferon and interleukin 4 by nearly all NK T cells in the liver and the majority of the spleen within 2 h. These cells mostly disappear by 5 h, and they do not reappear after 1 wk. Curiously, tetramer-positive thymocytes do not rapidly synthesize cytokines, nor do they undergo decreases in cell number after lipid antigen stimulation, although they express equivalent TCR levels. In summary, the data presented here demonstrate that-GalCer–specific NK T cells undergo a unique and highly compartmentalized response to antigenic stimulation.
